Objective
To study clinical presentation, disease severity, pregnancy complications, and maternal outcomes in women affected with COVID‐19 during the third wave as compared to the first and second waves of COVID‐19.
Methods
A retrospective, observational cohort study was conducted amongst 2058 pregnant and postpartum women with COVID‐19 admitted during three‐wave periods at tertiary care dedicated COVID‐19 hospital.
Results
The number of SARS‐CoV‐2 infected pregnant and post‐partum women with symptoms of COVID‐19 were four times higher during the third wave as compared to the first wave (OR=4.6, 95% CI, 3.5‐6.0, p <.001). There was a significantly lower proportion of pregnant and postpartum women with moderate to severe COVID‐19 during the third wave (0.6%, 2/318) as compared to those during the first wave (2.4%, 27/1143, p<.001) and second wave (14.4%, 86/597, p<.001). The ICU/HDU admissions during the third wave were significantly lower (2.5%,8/318) than those during the second wave (14.7%,88/597) [OR =0.2, 95% CI, 0.1‐0.3, p<.001] but similar to the first wave (2.4%,27/1143).
Conclusions
Decreased severity of COVID‐19, reduced maternal mortality, and morbidity were reported in the third wave as compared to the first wave and second wave of COVID‐19 in the Mumbai Metropolitan Region, India.
